Mushroom Onion Swiss Burger


My husband ate a burger while in Las Vegas some time ago and came home to tell me how amazing it was and that he must take me there to try it. So yesterday, remembering some of the ingredients he mentioned, I decided to make a similar burger and see if he would connect the dots. I did not, however, try to replicate it.

I was sneaky and never mentioned the burger he loved from Vegas, but after he took the first bite and immediately said “heey!” I knew I did good!! He was very pleased… it was pretty awesome.

Saute in skillet for about 7-9 min on medium heat.

Cut kaiser rolls and butter insides of both pieces, grill until golden brown.

Season with salt and pepper then fry burgers in skillet on med high heat on both sides until barely pink in middle. After the first flip, add 2 slices of swiss cheese to each patty and allow to melt completely.
